SOAP-MAKING APPARATUS.

Specification of Letters Patent.

Application filed December 3, 19l7, Serial No. 205,118. Renewed January 12, 1920. Serial No. 351,053.

This invention relates to the manufactureof soap wherein a fat or oil and an alkali are used as the principal ingliedients ind ng agen 1s used to bleach, oxidize, deodorize or purify the soap. It has for its objects to provide a single mechanism which will OOIIlblIlQ'lIl a proper manner the several ingredlents of the soap in a continuous process thereby. greatly decreasing the cost of the mechanism and the expense of its operation.

I attain these objects by the mechanism illustrated in the accompanying drawings,

. in which Figure l is a plan view of the mechanism and Fig. 2 is a view of one of the screens used in the ozonator.

' .The principal'elements of this apparatus admitted through inlets A? and ozone may be similarly admitted through inlets A to ozonator A. 1

As the liquid fat passes through ozonator A, it is moistened, heated, and subjected to the action of the ozone as desired. The fat is broken up and thoroughly mixed with the tankB. From tank B the .liquidlproduct is forced other materials by the steam and water and by the ozone. The steam-is forced into the mixture through sprays E, and the ozone through sprays F. After being forced by spraysE and F the fats, water and ozone are screened through screen G which is removably held in position by frame H. V The further mixture and application of steam and ozone and the further screening of the 7 composition is repeated twice in ozonator A.

As ,the product of ozonator A passes through separating tank B the air and.

steam vent off through vent B in thetop of by pump H through tube I and through filter press J and into agitator C where,

steam may be admitted. through inlet C and the product heated to thedesired temperature by the use of the steam jacket about the agitator to which steam may be admitted through inlet C Agitator C is'provided Patented May 4,1920,

with agitating blades C and means C for rotating the same.- Inlet C is adapted to oughly mixed at the desired temperature in agitator A, after which gate C is opened allowing the productto drain from agitator A into tank K from which the product is forced into ozonator D by pump L. In ozonator D the product of agitator C is subjected to the same treatment as the fat in ozonator A. Ozonator D is identical in construction with ozonator A. The product of ozonator D is a pure soap.

The apparatus now in common use provides for large settling tanks for the treat ,ing of the fats to remove impurities after the application of sulfuric acid or some other substance. Such apparatus is very expensive and requires along time for the- 'manufacture of'the product and large and expensive housing facilities.

I claim: a 1. A mechanism of the kind described admit the alkali simultaneously with the ad-' 4 mission of the fat product from filter J. The fat product'and alkali are then thor-- comprising a tank, several screens in the Y tank: adapted to divide the same intosum cessive compartments, means at the top of the tank for forcing a liquid into and through the compartments of the. tank, means for forcing a gas into. each of the compartments and an outlet from the tank adapted to permit the escape from the tank of the liquid and gas forced therein.

2. A mechanism of the kind described comprising a tank, several screens 'in the tank adapted to divide the same into successive compartments, means at the top of the tank for forcing a liquid intoand compartments, ad itioga'l means for forcing '1OO through the compartments. of the tank,' means for forcin a gas into each of, the:

a different gas into each of theconiparti mentsand an outlet from the tank adapted liquid and gas fo rced therein.
